How to convert PNG to JPG: For compatibility or editorial reasons you need to convert images from PNG to JPG but you don’t know which software to use? Do not worry. I’ll help you get the result home with as little effort as possible.

If you want to find out how to convert png to jpg, all you have to do is take a few minutes of free time and try one of the applications I’m about to recommend: they are almost all free (at least for non-commercial use) and can be used to work on hundreds of photos at the same time. I recommend, however, do not raise the compression level of the output files too much or you will cause a clear loss of quality in the images. Remember, too, that by converting photos from PNG to JPG you will lose all the transparency effects present in the latter.
